wrx average mpg

[Lenny]

Here in Illinois you can appear at court on the date assigned on the ticket
and get "court supervision" for about $150 for minor infringements. As long
as you aren't ticketed in the following set time (usually six months) it
never appears on your driving record. It seems like bribery to me, but I'm
not complaining. I have done it twice and I always get the Sec. of State
commendation for being a good driver. My mileage, btw, is about 22-24 with
a lot of both city and highway driving.

Cheers!

Hi SuperPoo: Did you do an AVE calculation which for me is relevant???
Thanks again for the good statistical analysis. ed

Ed,

In statistics "mean" means average. Whether that average is actually cruel
or not depends a lot on the values used to calculate it.

Hey Ed, what is an "AVE calculation"? Thanks.

The mean is the best mileage + lowest mileage divided by 2. The average is
the mileage of each fillup added together divided by the total number of
fillups. i.e. 23.6+19.3+25.1/3 = 22.66 mpg. Ed

Actually median is the midpoint between max and min. Mean is synonymous with
average.

Excerpted from http://www.dictionary.com/search?q=mean:

"The average value of a set of numbers."

This definition matches the definition in Bookshelf 2000 word for word.

My bound paper dictionary* lists these two definitions among many others:

"The middle point between two extremes"

and also

"A number that represents a set of numbers in any of several ways
determined by a rule involving all members of the set: average"

Two of the three dictionaries I consulted don't even bother to mention the
definition you imply, and the one that does mention it is the oldest of the
three. This and the fact that I wasn't even aware of that meaning (pun
intended) until looking it up leads me to suspect that it's on its way to
becoming archaic. Combine all this with the fact that the average of the
stated "min" and "max" numbers doesn't match the stated "mean" value, and it
seems likely to me that the OP's use of "mean" was, in fact, the average of
all the fuel economy values.

Hey Greg, do you live in Utah by any chance? You just described 90% of the
drivers here!!

We get a similar deal here in Utah if we also take a driver's safety class
with all the other "destination-oriented" drivers.

Uh, no ... the median is the number where half of the mileages are
better and half are worse.

And it doesn't make any sense to add up MPG numbers and then divide by
the number of samples. Yes, mathematically you can do that and get a
number, but it's not a useful number. Just add up all the miles, and
add up all the gallons, and divide one total by the other.

Ah, you're absolutely right, sorry for my error.

OK, but that number would be extremely close to the mean given (as the number of
gallons per tank is consistent). Showing the extent of variation adds
information by bounding the effects of seasonal variations from temperature and
gas formulation changes and a range of traffic congestion conditions.

I live in northern Michigan. But I'm pretty sure I described 90% of the
drivers everywhere except Germany.

I have been averaging about 22 mpg . 99% of my driving is on the
Interstate at 70 mph.

Three years in FRG taught me they are impatient,
but skilled drivers...as opposed to our typically
impatient, *unskilled* drivers ;-)
